This week’s edition of the Knowledge & Experience Series (Vol. 9 No. 6) featured an insightful presentation by Ing Sharon Quaye, who led a thought-provoking discussion on 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠 𝐭𝐡𝐞 𝐒𝐃𝐆𝐬: 𝐓𝐡𝐞 𝐀𝐟𝐫𝐢𝐜𝐚𝐧 𝐏𝐫𝐨𝐟𝐞𝐬𝐬𝐢𝐨𝐧𝐚𝐥’𝐬 𝐑𝐨𝐥𝐞, exploring how engineers can move beyond short-term project delivery to design and manage infrastructure systems that deliver long-term societal impact. She emphasized the importance of systems thinking, sustainability integration, and lifecycle-based planning in ensuring that infrastructure remains resilient, functional, and responsive to community needs over time.

Opening the discussion, she highlighted the persistent gap between project delivery and long-term performance, noting that infrastructure often performs well at commissioning but deteriorates over time due to weak maintenance planning and limited institutional ownership. She illustrated this with recurring challenges such as flooding roads and inefficient drainage systems, which point to deeper systemic issues rather than isolated technical faults.

The discussion traced sustainability thinking from global development frameworks through to the Sustainable Development Goals (SDGs), underscoring that while global targets are well defined, implementation remains the central challenge. Sharon emphasized that engineering serves as the critical bridge between policy intent and practical delivery, translating high-level aspirations into resilient, context-specific infrastructure systems.

A key theme was the need to embed sustainability across the entire engineering lifecycle. This includes strengthening problem definition during planning, ensuring context-driven and stakeholder-informed design, improving quality assurance during construction, and shifting from reactive maintenance to predictive, data-informed asset management. She stressed that success should not be measured merely by project completion, but by sustained functionality, resilience, and meaningful community impact.

The session further explored systems thinking as a core requirement of modern engineering practice, particularly the interdependence between infrastructure sectors such as water, energy, transport, and urban development. Engineers were encouraged to move beyond siloed project delivery and adopt integrated approaches that account for long-term resource flows, environmental constraints, and socio-economic outcomes.

Digital transformation was also highlighted as a key enabler of improved infrastructure delivery. Tools such as simulation platforms, digital monitoring systems, and data-driven planning tools were noted for their ability to enhance transparency, coordination, and decision-making. However, Sharon emphasized that technology must be supported by strong governance systems and skilled professionals capable of interpreting and applying insights effectively.

In addressing implementation challenges, she discussed the importance of strengthening procurement systems, improving supervision, and adopting lifecycle-based costing approaches. She also noted the need to balance technical excellence with affordability, local capacity, and long-term maintainability in infrastructure delivery.

A significant focus was placed on professional capacity development. Sharon emphasized continuous upskilling in both technical and non-technical competencies, including systems thinking, stakeholder engagement, sustainability integration, and data literacy, as essential for engineers operating in a rapidly evolving industry shaped by climate change and digital transformation.

In conclusion, the session reinforced that the future of engineering lies in designing and managing infrastructure as interconnected systems rather than isolated projects. Sharon called for a shift from output-focused delivery to outcome-driven impact, with sustainability, resilience, and accountability embedded across every stage of the engineering lifecycle.
